[Repost] Huawei Mate 20 Pro disassembly report: How to make wireless faster than wired? [Copy link]

The famous disassembly website iFixit recently released the disassembly report of Huawei Mate 20 Pro. Compared with Mate 10 Pro, the biggest change of Mate 20 Pro seems to be the front screen. Under the screen, there are modules required for structured light facial unlocking, as well as under-screen fingerprint recognition modules. On the back, there are three camera modules and 15W wireless fast charging modules...

It has been a while since the Huawei Mate 20 series went on sale, and many users have already received the new phones. According to tradition, it is time for the famous disassembly website iFixit to "dismember" it. Sure enough, they recently released the disassembly report of Huawei Mate 20 Pro.

So, now let's follow iFixit's perspective to see what new discoveries there are about this new Huawei flagship that "punches Apple and kicks Samsung".

As usual, before disassembling, the appearance of the Mate 20 Pro is compared with its predecessor, the Mate 10 Pro.

Compared to the Mate 10 Pro, the biggest change in the Mate 20 Pro seems to be the front screen. While further "full screen" and increasing the screen-to-body ratio, the Mate 20 Pro uses a hyperbolic bangs full screen in order to fit the sensors required for structured light facial unlocking.

On the back, the Mate 20 Pro's camera has been upgraded from dual to triple cameras, and the fingerprint recognition module on the back has disappeared due to the addition of under-screen fingerprint and facial structured light unlocking.

The bottom speaker of the Mate 20 Pro is integrated into the USB-C interface, so compared to the Mate 10 Pro, you will find that the several speaker holes on the left side of the bottom have disappeared, replaced by a newly designed SIM Card/NM Card slot inside.

After the comparison, it’s time to start disassembling. Unlike disassembling the iPhone, iFixit chose to disassemble the Mate 20 Pro from the back.

After using a hot air gun, a pry bar, and a suction cup, the glass back of the Mate 20 Pro was opened. Unlike disassembling the Mate 10 Pro, since the fingerprint recognition module on the back has been removed, there is no need to worry about tearing the cable when opening the back cover (this should also be the reason for choosing to start disassembling from the back shell).

After removing the back cover, the first thing you see is the Mate 20 Pro's two-way wireless charging coil. Huawei has never added wireless charging to its products before. On the Mate 20 Pro, Huawei not only directly came up with a 15W wireless charger, realizing "wireless is faster than some wired", but also added a reverse wireless charging function.

The motherboard is connected to other components via 9 cables. After removing it, we found that the Mate 20 Pro, like the P20 Pro, uses a relatively smaller motherboard in exchange for more space to cram in a larger battery.

Further remove the three rear cameras of the Mate 20 Pro from the motherboard

Upper right: 40 megapixel F1.8 equivalent to 27mm wide-angle camera Lower right: 20 megapixel F2.2 equivalent to 16mm ultra-wide-angle camera Lower left: 8 megapixel F2.4 equivalent to 80mm 5x optical zoom camera

[p=28, null, After removing the camera module from the motherboard, we can also see the contents on the motherboard more clearly:

Red: Toshiba THGAF8T0T43BAIR 128 GB Universal Flash Memory
Orange: HiSilicon Hi6421 Power Management IC
Yellow: Skyworks 78130-21 WCDMA / LTE Band Front-End Module 8/12/13/20/26/27
Green: Skyworks 78132-52 WCDMA / LTE Band 7/30/40/41 Front-End Module
Blue: Skyworks 78131-21 WCDMA / LTE Band 1/2/3/4/25/34/39 Front End Module
Dark blue: Skyworks 7360-2A 04115.1 1821 MX RF Module
Purple: HiSilicon Hi6422 Envelope Tracker

Turn over the back of the motherboard:

[p=28, null,left]

Red: Hynix H9HKNNNEBMBUDR-NEH LPDDR4 (Kirin 980 may be below this)
Orange: NXP 80T37 (probably NFC controller)
Yellow: HiSilicon Hi1103 Wi-Fi chipset
Green: HiSilicon Hi6363 RF transceiver

As mentioned in the comparison with Mate 10 Pro at the beginning, due to the addition of structured light facial recognition function, Mate 20 Pro adopts the notch screen design. Due to the addition of facial structured light recognition module, Mate 20 Pro not only makes the phone more secure in terms of unlocking and secure payment. At the same time, because of its ability to recognize three-dimensional features, in conjunction with NPU, the Mate 20 Pro can also achieve real-time modeling of objects.

After disassembling, we can finally get a glimpse of what’s underneath the bangs:

Red: Dot projector
Orange: The same 24-megapixel F2.0 equivalent 26mm front camera as the P20 series
Yellow: Distance sensor
Green: Floodlight sensing element
Blue: Ambient light sensor
Light blue: Infrared camera
Purple: Unknown

To go with the new card slot design, Huawei also introduced a new memory card standard at the press conference: NM Card. The full name of NM Card is "Nano Memory Card". Its size and shape are consistent with the Nano SIM Card we commonly use. The new card slot on the Mate 20 Pro can insert a main Nano SIM card while inserting another Nano SIM card or an NM Card on the back.

In addition, the new NM Card provides a maximum read speed of 95MB/s and is currently only produced by Huawei itself.

Like the P20 Pro, the Mate 20 Pro's USB-C port is mounted on a flexible cable. This means that if the port fails and needs to be replaced, the repair cost will be lower than if it is mounted on the component board like the Pixel 3 XL.

Long battery life has always been a feature of the Mate series, and the Mate 20 Pro is equipped with a large 4200mAh (16.05Wh) battery. Compared with the flagship models of various manufacturers this year, the Mate 20 Pro maintains its leading position in battery capacity: iPhone XS Max: 15.28Wh Galaxy Note 9: 15.4Wh 387059 The remaining screen can be separated from the frame by heating it with a hot air gun and using a prying piece. This time, the Mate 20 Pro uses a 3120X1440 pixel screen with a 19.5:9 pixel density of 538 ppi.

A new under-screen fingerprint recognition module is also found under the AMOLED panel. The optical fingerprint sensor is provided by Goodix.

Finally, iFixit made some comments on the internal structure and repairability of Huawei Mate 20 Pro:

Since many components inside the phone are modular, it is convenient for replacement.

If you need to replace the battery, just remove the panel and the middle frame.

If the screen is broken, it probably means that the fingerprint recognition module needs to be replaced at the same time, and vice versa.

As for the repairability score, iFixit gave it a 4. (10 points out of 10, the higher the score, the easier it is to repair, the iPhone XS series is 6 points.)

To go along with the new card slot design, Huawei also introduced a new memory card standard at the press conference: NM Card. The full name of NM Card is “Nano Memory Card” and its size and shape are consistent with the Nano SIM Card we commonly use. The new card slot on the Mate 20 Pro can accommodate a primary Nano SIM card and either a second Nano SIM or a NM Card on the back. In addition, the new NM Card offers a read speed of up to 95MB/s and is currently manufactured exclusively by Huawei. Like the P20 Pro, the Mate 20 Pro's USB-C port is mounted on a flexible cable. This means that if the port fails and needs to be replaced, the repair cost will be lower than if it is mounted on the component board like on the Pixel 3 XL.
